1 Overview
The UfiSpace S9501-28SMT is a high-performance, versatile open networking white box
router that is designed to address the changing needs of backhaul transport requirements
as Telecoms make the transition from legacy technologies towards 5G. It enables telecoms
and service providers to deploy disaggregated open network infrastructure to lower costs
and rapidly scale existing services for edge computing, mobile backhaul, and broadband
access applications. The S9501-28SMT is future-proofed with a powerful quad-core
processor, 28 high-speed interfaces, and full timing features supporting IEEE 1588v2 and
SyncE. It is suitable for both indoor and outdoor deployments with redundant, hot-
swappable components for convenience, increased availability, reliability and lower costs
of maintenance
This document describes the hardware installation process for S9501-28SMT.

2.2 InstallaonEnvironmentRequirements
•Power Reserve: The S9501-28SMT power supply is available with:
1. DC Version: 1+1 active-active -48 voltage DC power supply field replaceable unit or;
2. AC Version: 1+1 active-active universal 100-240V AC power supply field replaceable unit.
To ensure the active-active feed power design functions properly, a field with dual power
circuit is recommend and a reserve of at least 200 watts on each power circuit.

•Space Clearance: The S9501-28SMT chassis width is 17.32 inches (44cm) and shipped
with a rack mount brackets suitable for 19 inch (48.3cm) wide racks. The depth of the
S9501-28SMT chassis is 11.89 inches (30.2cm) without the field replaceable units (FRUs)
and comes with adjustable mounting rails suitable for rack depths of 22 inches (55.88cm)
to 33 inches (83.82cm). The handle for the fan units will extend outwards by 1 inch
(2.54cm) and the handle for the power supplies will extend outwards by 1.5 inches
(3.81cm). Therefore, to accomodate the fan and power supply handles, a minimum space
clearance of 2 inches (5.08cm) is needed at the front and back of the S9501-28SMT.
A total minimum reserve depth of 16 inches (40.6cm) is required.

Caution
It is recommended that installation be done by two trained professionals. One
individual should hold the equipment in position on the rack while the other secures it
in place.
1. Secure the rack mount brackets onto the router.
Align the rack mount brackets with the holes provided on the both sides of the case and
secure the brackets using the 8 M4.0*L6.5mm screws provided with the package.
2. Secure the router onto the rack posts.

4. Carefully slide the new fan module into the fan bay and gently push until it is flush with
the case.
5. Secure the captive screw on the fan module to lock the fan in place.
The fan modules are hot swappable field replaceable units (FRUs), which can be replaced
while the router is operating as long as all the remaining modules are installed and in
operation. The fans come pre-installed and the following steps are instructions on how to
install a new fan module.
1. Loosen the captive screw located on the fan module.

Caution
Shock hazard!
For safety, please disconnect all power inputs from the power supply unit before
servicing the router.
1. Locate the release tab on the PSU. Then press and hold down the release tab to unlock
the PSU from the power bay.
2. While holding down the release tab, grip the PSU's handle and firmly pull it out of the
power bay.

correct position.
4. Carefully slide the new PSU into the power bay and gently push until it is flush with the
case.
5. An audible click will be heard when the PSU is installed correctly. The PSU will not go in all
the way if it is in the wrong direction.
Note
The PSUs must have the same airflow direction as the installed fans (front to back).

(12.7 +/- 0.5mm)
Crimping Tool
Grounding Lug
Figure24.
Warning
This equipment must be grounded. Do not defeat the ground conductor or operate
the equipment without correctly grounding the equipment. If there is any uncertainty
about the integrity of the equipment's grounding, please contact the electrical
inspection authority or a certified electrician.
1. Before grounding the router, ensure that the rack is properly grounded and in
compliance with local regulatory guidelines. Ensure that there is nothing that can obstuct
the connection for grounding and remove any paint or materials that may prevent good
grounding contact.
2. Strip the insulation from a size #6 AWG grounding wire (not provided within the package
contents), leaving 0.5” +/-0.02” (12.7mm +/-0.5mm) of exposed grounding wire.
3. Insert the exposed grounding wire all the way into the hole of the grounding lug
(provided with package contents).
4. Using a crimping tool, firmly secure the grounding wire to the grounding lug.
It is recommended that equipment changes be done on a grounded rack system. This will
reduce or prevent the risk of shock hazards, equipment damage, and potential of data
corruption.
The router can be grounded from the router's case and/or the power supply units (PSUs).
When grounding the PSUs, ensure that both PSUs are grounded at the same time in case
one of them is removed. A grounding lug and M4 screws and washers are provided with the
package contents, however, the grounding wire is not included. For convenience, there are
two locations on the case in which the grounding lug may be fixed.
The following instructions are for grounding the router.
